New Application Method of Static-Field Magnetization to Magnetically Levitated Mover System With High T c Superconductors

Application method of static-field magnetization to magnetically levitated mover system with high critical temperature ( T c) superconductors is discussed. The system is composed of a levitated mover, magnetic rails, a linear induction motor (LIM) and some power supplies. In the paper, static-field magnetization is applied to superconductors in the levitated system from bottom superconductor surfaces. Then, magnetizations in superconductors are tried to control using static-field on superconductor surfaces. That is, magnetic flux density distributions are successfully forced to change to initial flux density distributions.
